I have never told my wife she couldn't have something. If she wants to spend money on something I ALWAYS tell her I am happy for her to have whatever she wants. She has NEVER spent this kind of money on a purchase and then refused to tell me what it was for. I have never done that either. It wasn't so much that she had spent the money. It was that she didn't tell me about it. And then when I discovered it, she hid what the purchase was.

She is telling me that we have a trust issue in our marriage. This does nothing to build trust. It is damaging it even further.
